Will Retin-A (Trentinoin ) Even out Skin Color? I'm Left With Old Scars and Acne on Dark Skin.

My skin is Dark skinned, around the side of my face is Dark from old scars and acne, around my eyes is lighter then my forehead and my T-Zone is also lighter then the rest of my face. Will Applying Retin-A return my face to one original color?
